These trends are totally in these days ...but get a sharara stitched for your wedding .. you could later pair up the same long shirt with culot ..but since it's your special day ..so it should be a sharara to look different than other girls wearing culots on your wedding

you should opt for a sharara, with heavier shirt and less work on the sharara..its very much in fashion and u can pair ur shirt later with pants..
there is a hardly any time left in ur shaadi, soo hurry girl,,these things take time
wish u all the best
